[linux-lvm] clvmd: activating local vg in cluster fails

[Hal Martin]

Hello all,

I have a two node pacemaker/corosync cluster running clvmd. The two
nodes have both local and SAN storage available to them. With DLM and
clvmd running I can activate or deactivate LVs on the SAN VG, but not
on local VG. LVM2 version 2.02.88, lvm.conf locking_type = 3

However I cannot access the logical volumes through
/dev/system/$lvname or /dev/mapper/system-$lvname

lvchange also fails:
